To prepare chicken, coast chicken with marinade. Cover and refrigerate 4 hours or overnight.

Preheat oven to 350°F.

Season chicken with salt and pepper, place on rack in roasting pan. Wrap garlic in foil and place alongside chicken. Roast 1 1/2 hours or until a meat thermometer inserted in thigh registers 170°F. Remove from oven and let rest 20 minutes.
